this is my presentation in advanced hydraulics about water quality models containing basic descriptions about major used models.

22. • Network Flexibility
• Most Water Quality Problems
• Separation of Processes
• External Links to Models and Spreadsheets
• Two Solution Techniques

23. • Does not handle some variables and processes:
– Mixing zone processes
– Non aqueous phase liquids (e.g., oil spills)
– Segment drying (mudflats, flood plains)
– Metals speciation reactions (special module, META4,
not part of general WASP release)
• Potentially large external hydrodynamic files
• Separate eutrophication and toxicant fate
modules
• Cannot readily be run in batch mode
